Abstract: 466,180. Compressed-air engines; governors. USKSIDE ENGINEERING CO., Ltd., and WOOD, J. W. Nov. 21, 1935, No. 32325. [Classes 57, 122 (ii), and 122 (iii)] In a compressed-air engine wherein the crank-shaft is disposed centrally between pairs of opposed cylinders, the distribution is effected by a rotary valve preferably geared to the crank-shaft, and adjustment and reversal are effected by a ported, rotatable sleeve surrounding the valve. The engine has pairs of opposed cylinders 6a, 7a in line. The pistons are connected to the crank-pins which carry roller bearings, by off-set, inclined rods. The centrally-arranged shaft is mounted in ball and roller bearings. The distribution is effected by a rotary valve 18 the opposite ends 19 of which are mounted in ball bearings. The cut-off and reversal are controlled by a surrounding-sleeve the ends of which are secured to discs 23a, 23b carrying square pins 24a, 24b. The pin 24a is secured to a hand-controlled disc 25. The sleeve is turned 110‹ to effect reversal. The valve has admission and exhaust ports 28, 29 respectively, and the cylinders passages 30, 30a, 31. A part of the exhaust is controlled by the pistons. The valve is driven by a skew gear wheel 38 from the crank-shaft which also drives a governor comprising a lower part 42 mounted in ball-bearings 44a and an upper sleeve 42a mounted by ball-bearings in the sleeve of a control valve 50a the spindle of which is moved longitudinally against the resistance of an adjustable spring 53 by the governor levers 47, 52.

Title: Treatment of urea-formaldehyde and aminotriazine-formaldehyde condensation products modified by an aliphatic alcohol
Inventor: COVENEY LEONARD WINSTON
IPC: C08G12/42
Filed: 1948-12-18
Abstract: Etherified urea- and amonotriazine-formaldehyde condensation products having improved hardness and water resistance are obtained by heating said condensates in the presence of inert non-hydroxylic solvents boiling below 300 DEG  C. until a compatible solution is formed.  Up to 20 per cent of an alcoholic solvent may be present, the alcohol having a lower boiling point than the non-hydroxylic solvent. Suitable non-hydroxylic solvents are aliphatic or aromatic hydrocarbons, ketones and esters.  In examples: (1) 400 parts butylated urea-formaldehyde resin (50 per cent by weight in a 1 : 1 mixture of xylol and n-butanol) and 900 parts xylol were mixed and heated to remove 800 parts distillate in 1 1/2 -2 hours the temperature reaching 130-135 DEG  C.  On cooling the product set to a hard brittle mass which could be easily melted and thinned with xylol; (2) a mixture of butylated melamine-formaldehyde resin and white spirit was similarly treated; (3) 400 parts 50 per cent butylated melamine-formaldehyde resin was heated under vacuum to remove 150 parts distillate, 400 parts white spirit were then added and the mixture refluxed at 145 DEG  C. for 5 hours; (4) as in (3) using di-isobutyl ketone as solvent.

Title: Improvements relating to the sealing of electrical conductors into gasfilled quartz containers
IPC: C03C27/04
Filed: 1932-11-21
Abstract: 411,933. Sealing leading-in wires into vitreous envelopes. BRITISH HANOVIA QUARTZ LAMP CO., Ltd., Slough, Bucking- hamshire. Nov. 21, 1932, No. 32914. Convention date, March 8. [Class 39 (ii).] In sealing a metal conductor into a gas-tight fused quartz container, the conductor 3 is enclosed within a fused quartz sleeve 4, the bore of which affords a clearance or recess 6 around the conductor for a portion of the length thereof, and a sealing-compound 5 is applied around the conductor to extend into the clearance or recess. In forming the clearance in the bore one end of the sleeve 4 is closed temporarily either by fusion or a suitable stopper, and the other end is connected to an exhaust pump to evacuate the sleeve. The evacuated sleeve containing the metal core is then heated to the working temperature of fused quartz, about 1650 C., either by flames or electric heating, that portion of the sleeve which will ultimately be on the atmospheric side of the conductor being heated first. The heating is continued along the sleeve, the intensity of heating being increased as the end A of the sleeve is approached, after which the conductor is cooled to room temperature. The quartz sleeve and conductor are next attached to the quartz vessel or container and the sealing compound 5 is introduced into the gap between the conductor and sleeve. The sealing compound used may be prepared from a mixture of the higher hydrocarbons found in coal tar and the carbonaceous materials resulting from the distillation of petroleum, it being necessary for the material to be highly elastic and compressible, firmly adherent to metal and quartz, not absorbent of, nor permeable by, moisture and gas, and capable of melting at moderate temperature with a gradual change in viscosity. At 100 C. the sealing compound should also have a viscosity coefficient of approximately 20,000 dyne-seconds per square centimetre. The conductor may be in the form of a bar, ribbon, rod, or wire, and may consist of tungsten, molybdenum, platinum, or other metal which melts above the working temperature of fused quartz.

The carrier 1 which comprises a self propelled truck is driven into the drying chamber with the bricks on the boards 10 and the stages in line with the truck so as to enter the doorway. The stages 7 are then raised and rotated between the bars 19 to lie across the chamber. The stages 7 are lowered to rest the boards 10 on the bars 19 and the truck can be driven out of the chamber to be re-loaded. To facilitate loading transportable racks 4 are provided (Fig. 9) having vertical limbs 33 with supporting members 30 for the boards 10, the bricks from the press being loaded on to these racks after which a truck carrier 1 can be driven into the rack to pick up a load. The trucks 1 may have road wheels 14, 15, which run between guide tracks in the drying chambers or they may have wheels running on rails. In the Specification as open to inspection under Sect. 91 are described a suspension truck running on an overhead track and having rotatable stages raised and lowered by means of levers, and transportable racks similar to the racks 4 but carried on overhead rails. This subject-matter does not appear in the Specification as accepted.

The substance contained in the fluid comprises finely-divided copper coated with a macro-molecular compound. The compound is prepared by mixing the copper with a solution of collodion in acetone, evaporating the acetone and grinding the mass thus obtained. The pulverulent substance resulting from this operation is then mixed with water containing a wetting agent to prevent agglomeration.
